- remove duplicated code and headers
- add option allowing arbitrary SDRAM/DDR Timing parameters.
- mark automatically calculated timings as EXPERIMENTAL
- fix comment header block
Related to BUGs:
- kernel boot up fails with CONFIG_BFIN_KERNEL_CLOCK item on.
- kernel does not boot if re-program clocks
[ Mike Frysinger <vapier.adi@gmail.com>
- fix comment header
- mark do_sync static
- document the DMA shutdown
- simplify SIC_IWR handling
- fix ANOMALY_05000265 handling to work as intended ]

reprogramming clocks
As pointed out by Appalayagari Sreedhar, make sure we include the fix
for SPORT hysteresis when reprogramming clocks.

- Disable all bits in SIC_IWR unless we are going into a real (DPMC)
power saving mode. Any Interrupt can wake the core form it's idle state.
- Remove deep sleep mode as it is not going to be used anywhere:
We support sleep, sleep deeper and hibernate.

Don't write conflicting data to EBIU_SDBCTL after the SDRAM is
configured. This can cause data corruption, since we might change SDRAM
row and column addressing modes.

files
theres no need to declare ram{end,start,base} in the head.S files
when declaring them with the other memory related variables in setup.c
is so much simpler/nicer
